Renal disorder impairs glomerular filtration that resulted to fluid overload. With fluid volume excess,hydrostatic pressureis higher than the usual pushing excess fluids into the interstitial spaces.Since fluids are notreabsorbed at thevenous end, fluid volume overloads the lymph system andstays in theinterstitial spacesleading the patient tohave edema, weightgain, pulmonary congestion and HPN at the same time dueto decrease GFR,nephron hyperthrophizedleading to decreaseability of the kidney to concentrate urine and impaire dexcretion of fluid thus leading to
